nsssavva.

To all whmit it may concern:

Be it known that I, FRED H. DANIELS, of Worcester, Worcester county, Massachusetts,

of which the following is a full, clear, and exact description, reference being had to theaccompanylngdrawings, forming part of this specification, in whichigure' 1 is a plan view, largely diagrammatic, of a steam engine and its vacuum pump and condenser, embodying my invention; Fig.2 is a side elevation of thesame; and ig. 3 is an enlarged elevation ofthe valve mechanism.

My invention has relation to steam engines of t e condensing type, and more particularly to reversing engines, These engines run intermittently, being operated rapidly in one 'rection for a period of time, and then reversed to run rapidly in the other direction,

or they may stop and stand .idle for a numberbeen custom- I of minutes. H'eretoforeit has ary to operate the which condense the steam from this type of engine continuously, which involves the expense of continuously pumping the water supplied there- .to. e present invention is designed to ob gine and of the condenser pump are simultaneously controlled, so that the condensing apparatus is started and stopped with the engine, and is, furthermore, operated at all times relatively to the operation of the engine. I

consists in the novel of parts, all substantially as hereinafter described and pointed out in the appended claims.

In the drawings, 2 designates a steam engine of any suitable type, 3 is the main steam supply pipe therefor, in which is located the main throttle or governing valve 4, operated I by throttle lever 5 connected to its stem in the usual manner. 6 designates a condenser and vacuum. pump, which may also be of any suitable character, and which receives the exhaust steam from the engine 2 through the exhaust pipe 7. The vacuum pump receives its steam supply through a pipe 8, which is shown as being a branch of the pipe 3, being connected thereto above the throttle valve 4.

he pipe 8 is provided with a governing Specification. of Letters Patent. Application filed April 2'7,

valve 9, of any suitable character, such as a butterfly valve, and its stem is provided with a lever arm 10 which. is connected by a link 11 with a lever arm 12 on the stem of the throt--- tle valve 4. I

13 is a by-pass pipe leading around the governing valve 90f the steam supply pipe 8.

are also arranged to synchronize with each other so that the amount of opening for the supply of steam to the vacuum pum is directly proportionate to the amount 0 open The speed'of'. t 1e vacuum pump is, therefore, at all'times' he main throttle valve.

such as to insure the condensation oi whatever amount of steam is exhausted froni 'the 14 are provided. in order that when themain engine throttle valve is closed, a small amount of steam may nevertheless be su plied to the vacuum pump in order to hold the vacuum in the exhaust pipe and to con dense the small quantity 1 passes through the main engine by leakage,

etc. the valve 14, or any desired speed of the vacuum pump can be maintained b T the adiustment of this valve, valve 9, when desired.

The advantages of my from the increased economy in operation due to the ability to control the operation of the condenser relatively to theoperation of the mainengine. The

securing this result. i .As above indicated, my invention is applicable to various types of engines and condens ers, and various changes may be made in the arrangement and connection of the valves r without departing irom the spirit and scope of my invention. What I claim l 1. A steam engine having a condenser englue, and means for governing the sp eed of the condenser engine in proportion to the-speed y as described- 2. A steam engine having a condenser en- 8o by-pass pipe 13 andfits v'alve This by-pass can be cut out by closing invention result IIO gine, and means for governing the supply oi live steam to the condenser engine in proportion to the supply of live steam to the main engine, suliistantially as described.

3. A steam engine having a condenser engine, and. means for governing the speed of the condenser engineby and in proportion to supply of the engine and pump; substantially as described.

8. In a steam engine, a main throttle or goveri'iing valve for cont-rolling the steam supply thereto, a steam pump for operating the engine condenser, a valve for controlling the supply of steam to said pump, and means the speed of the engine, substantially as defor simultaneously operating the said valves; scribed. substantially as described.

4, A steam engine having a condenser en 9. A steam engine having a main throttle gine, steam supply pipes for the main engine valve, a'condenser for the engine, a steam and the condenser .engine, and means com mon to the two steampipes for simultaneously and proportionately controlling the supply of live-steam to the main engine and the condenser engine, substantially as described.

5. The combination of a steam engine, a condenser therefor, a supply-pinup for the condenser, and means for automatically controlling the speed of the pump simultaneously with that of the engine; substantially as depump for supplying water to the condenser, a controlling valve for the steam supply of said pump, means for operating'said valves in unison, and means i or regulating the steam supply to the pump independently of the said valves; substantially as described.

10. A steam engine having a main throttle valve, a condenser for the engine, a steam pumpfor supplying the condenser, a main valve for controlling the steam supply to the pump, means for operating said valves in unison, and a valved by-pass around the last named valve and affording inde )endent means for controlling the steam supply of the pump; substantially as described.

- In testimony whereof, I. have hereunto set my hand.

6. The combination of a steam engine, a condenser therefor, a pump for supplying the condenser, an engine/tor operating the pump, valves for controlling the supply of live steam to the engines, and means for synchronizing the operations of said valves; substantially as described.

7. The combination of a steam engine, a condenser, a pump for supplying the con-- denser, and connected valve mechanism for simultaneously controlling the live steam FRED H. DANIELS.
